最近在学习慕课网的课程《Java遇见HTML——JSP篇》,简单做些记录。
课程网址为:http://www.imooc.com/learn/166
六、 Session对象
七 application对象
代码:
- <%@ page language="java" import="java.util.*" contentType="text/html; charset=utf-8"%>
- <%
- String path = request.getContextPath();
- String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
- %>
- <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
- <html>
- <head>
- <base href="<%=basePath%>">
- <title>My JSP 'application.jsp' starting page</title>
- <meta http-equiv="pragma" content="no-cache">

- </head>
- <body>
- <h1>application对象</h1>
- <%
- application.setAttribute("city", "北京");
- application.setAttribute("postcode", "10000");
- application.setAttribute("email", "lisi@162.com");

- application中的属性有:<%
- Enumeration attributes = application.getAttributeNames();

- }
- %><br>
